[Study on the apical sealability of warm lateral condensation techniques]

An apical leakage test and a visible light spectrophotmetric analysis were performed to compare the apical sealability of warm lateral condensation and conventional lateral condensation techniques.The results showed that warm lateral with sealer delivered best sealability.It was superior to warm lateral without sealer(P<0.05) and conventional lateral condensation technique(P<0.01).Because of its inconvenient operation causing by native-made putta-percha,it is difficult to use warm lateral condensation technique widely in our country.
